Re: Can you say you made money if you never actally sell your coins?
Should you hodl forever? Does everyone have a price? What is yours? 
If what you invested in(bought) does have a good future in your opinion, it's better to sell some portion of it and keep the rest for the possible bigger moves up, it's sort of dollar cost averaging but instead of buying more when the price goes down, you're selling some every time price goes up.
Of course it's not a very smart move to not sell anything at all while you're up 3-5-10x, unless you don't care about losing the profit you got so far from that investment and you're okay with losing your profit as it can happen specially with shitcoins.
With shitcoins, then that opportunities will be lost forever but with solid project we already witness how high those top alts and bitcoin
went thru. A matter of how good you understand everything.
Your call should always accompanied by your knowledge, it lessen or avoid you to lose your investment. Most of those long term investors
believes that the project will bring them fortunes.
